Bimetal Thermometer Afriso BiTh 80, Ø80 mm, 0–120°C, stem 150 mm, G1/2'' axial, class 2

The Afriso BiTh 80 bimetal thermometer is a mechanical temperature instrument with an 80 mm dial, a measuring range of 0–120°C and a 150 mm insertion stem. It has an axial G1/2" connection and accuracy class 2, designed for direct temperature monitoring in heating, ventilation, air conditioning and industrial installations. The design allows installation on panels or pipe lines where electrical power is not available or not desired, providing robust, maintenance‑free measurement based on bimetallic strip technology.

Advantages

The bimetal thermometer provides a simple, reliable temperature readout without requiring power, offering mechanical durability and resistance to typical field conditions. Its 80 mm dial delivers clear visibility, while the 150 mm stem and axial G1/2" connection facilitate installation in standard process and HVAC applications. Class 2 accuracy ensures consistent readings suitable for monitoring and control tasks where moderate precision is acceptable.

Suitable for

• Temperature monitoring in heating systems and boilers
• HVAC ducts, panels and distribution manifolds
• Industrial process lines and equipment where electrical sensors are impractical
• Panel mounting and direct pipe insertion with standard G1/2" connections

Key specifications

• Dial diameter: 80 mm
• Measuring range: 0–120 °C
• Stem length: 150 mm
• Connection type: axial G1/2" thread
• Accuracy class: 2
• Sensing element: bimetallic strip
• Mounting options: panel or direct pipe insertion

How to use

Install the thermometer by screwing the axial G1/2" connection into a compatible socket or pocket on the pipe or fitting. Ensure the 150 mm stem is sufficiently immersed in the medium to reflect the actual process temperature, and secure the instrument against vibration. Mount the dial so it is visible for regular reading; panel mounting may require a compatible cutout or mounting bracket. No electrical connection is required; the device gives an immediate mechanical reading when the medium temperature changes.

Usage recommendations

For best performance, avoid placing the stem in high‑velocity flow without protection, and ensure the selected insertion length allows the sensing element to be immersed in the medium. Use appropriate pockets for frequent removal, and verify readings periodically against a calibrated reference if accuracy better than class 2 is required for your application.
